Re: mss.c pcm fix to ' attach returned 6 ' load failure for v5.x acpi and up

John,

P.P.S.  The code in mss.c that gave rise to the working acpi boot in the 
P.S. (per the manual requirement) is

static struct isa_pnp_id mss_ids[] = {
         {0}
};
static int
mss_probe(device_t dev)
{
         u_char tmp, tmpx;
         int flags, irq, drq, result = ENXIO, setres = 0;
         struct mss_info *mss;
printf("mss_probe: bus %s is probing device 
%s\n",device_get_nameunit(device_get_parent(dev)),device_get_nameunit(dev));
         result = ISA_PNP_PROBE(device_get_parent(dev), dev, mss_ids);
         if (result!=ENOENT) return ENXIO; /* only continue if the device 
is not pnp */
         /* old way- not so good for ACPI: */
         //if (isa_get_logicalid(dev)) return ENXIO;
printf("mss_probe: non pnp audio chip detected.\n");
